T 0 all 1071 0117 it may concern:

Be it known that l, Elsi-men C. KnooAN, a citizen ot the United States, residing at South Bend, in the county of Joseph and State of Indiana, have invented certain new and useful improvements in Windowi tlashes, of which the following is a specification.

The ini ention relates to window sashand has for its object to provide a window sash so constructed that panes of glass may be held therein in such a manner that the use oi putty is eliminated, thereby providing means tor holding the glass in place which will withstand great shock, such for instance as is common in shop construction, and especially in places where heavy machinery, rich as drop hammers and the like are used, and the incessant pounding of which set up a vibration which soon shakes putty loose and breaks much glass.

A further object is to provide means for holding window panes resiliently, thereby obviating breakage of the panes incident to shock.

A further object is to provide a window sash so constructed as to permit broken panes to be easily and quickly replaced through the medium or" clamping members. Also to provide a window pane holding device for. windows so constructed that the use 01? putty is obviated, which putty in case of fire soon crumbles and allows the pane to drop from the sash, and consequently admit dra'lts to the fire.

A further object is to provide a window sash inullion T-shaped in horizontal cross section, on one flange of which is slidably mounted a U-shaped channel having outwardly extending flanges, between which flanges and the other flanges of the mullion, the adjacent ends of window panes are received. Also to provide registering apertures in the Ushaped channel and the flange of the rnullion in which apertures a transverse portion of a ttshaped clamp is loosely mounted, the arms of which clamp terminate in hooked spring portions which are adapted to be forced into engagement with the flanges of the U-shaped channel for clamping the adjacent edges ot the window panes into position.

With the above and other objects in view claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

in the drawings nigure l is a front elevation of a portion of a window sash mullion showing the invention applied thereto.

2 is a horizontal sectional View taken on line 2-2 of Fig. 1.

Fig. 3 is a vertical sectional view taken on line 33 of Fig. 1.

Fig. l is a perspective view of flexible U-shaped clamping member.

Referring to the drawings, the num ral 1 designates a mullion of a window sash, which inullion is T-shaped in horizontal cross sec tion as shown in Fig. 2, and comprises flanges 2 which are in the same vertical plane and the flange 3 which is disposed at a right angle to the flanges 2. Disposed on the flange 8 1s a U-shaped channel i, the flanges 5 hi" which channel terminate in outwardly extending flanges 6, which are preferably in parallel relation to the flanges 2 of the mullion, and between the flanges 6 and between the flanges 2 of the inullion the adjacent sides 7 of window panes 3 are disposed and are adapted to be held resiliently in resilient packlng members 9, which are tl-shaped in cross section and disposed on the adjacent edges oi the pane. The packing members may be formed from ielt, rubber or any other packing material, however the material used is preferably a resilient one, which re silient material will take up shocks where the construction is used in connection with factories, and consequently prevent breal age of the glass and eliminate the use of putty, which putty if jarred loose releasing the glass and allowing the same to fall and break.

Extending through re storing apertures 10 in the flanges 5 in the channel member 4i, and through a registering aperture 11 in the flange 3 of the lnullion is a transverse portion 12 of the pivoted ii -shaped clamping member 13, the lei of which terminate in flexible curved members 15, which members when the clamping members are moved to the positions shown in 3, engage the outwardly extending flanges 6 of the chanthe invention resides in the combination and -nel member at and force said flanges into arrangement of parts as hereinafter set forth, shown in the drawings, described and binding engagement with the packing members 9, thereby securely holding the ad acent v the panes in such a manner that any loose edges 7 of the window panes 8 between the flanges 6 of the U-shapcdchannel i, and theflanges 2 of the mullion. It will be seen by referring to Fig. 3 that when the U-shaped clamping members 13 are moved into clamping position, that a the curved portions 15 thereof will flex, thereby resiliently holding flanges 3 of the mullion, thereby allowing a range of clamping action when the clamping members are moved into clamping position as shown in Fig. 3.

From the above it will be seen that awindow pane holder is provided for sash which. is particularly adapted for use in factories where windows are subjected to constant vibration, which vibration loosens the putty of conventional forms of windows and causes the panes of glass to drop from the windows and become broken. it will also be seen that a window pane fastener is provided which obviates the use 01" putty, thereby overcoming the difliculty now'experienced in case of fire where putty when subjected to intense heat crumbles, thereby allowing the panes to drop from the windows and consequently allowing the spread of fire.

The invention having been set forth wha is claimed as new and useful is r 1. A window pane holding device comprising a member T-shaped in cross section, a U-shaped channel disposed on one of the flanges of said T-shaped member, outwardly extending flanges carried by the-flanges of the U-shaped channel and disposed adjacent the flanges or" the T-shaped member,

said flanges of the U-shaped channel and the T-shaped member being adapted to receive therebetween adjacent edges of window panes, U-shaped clamping members having their transverse portions disposed in apertures of the T-shaped member and channel member, the arms of said U-shaped clamp ing members terminating in curved flexible members, said curved flexible members be ing adapted to be forced into engagement with the outwardly extending flanges of the channel member, thereby forcing said channel member inwardly;

2.7The combination with a window sash mullion T-shaped in horizontal cross section and having one of its flanges disposed between adjacent edges of window panes,ot

1 ,ao eee means for holding'said panes in said mullion, said means comprising a U-shaped channel member disposed on the flange of the mullion which is disposed between the panes, a U-shaped clamping member extending through enlarged registering apertures in said channel member and mullion flange, said clamping member having its arms provided with flexible members, and outwardly extending flanges carried by the U-shaped channel member and adapted to be engaged by the flexible members of the arms of the U-shaped clamping members.

3. A window pane holder comprising a T-shaped mullion, a U-shaped channel disposed on one flange of said mullion and provided with outwardly extending flanges registering with the other flanges of the mullion, resilient members disposed between'the flanges of the mullion and the flanges of the U-shaped channel for the reception of adjacent edgesot window panes, and a U-shaped clamping member having its transverse portion extending through enlarged registering apertures in the Ushaped channel and the flange of the mullion, said clamping member having its arms so proportioned that when they are forced inwardly they will engage the outwardly extending flanges of the channel'member and storce said chan arms of said U-sha ed clam ain member:

being so proportioned that when they are forced inwardly they willengage the flanges of the channel membe and force the channel member inwardly.

5. The combination with a T-shaped mullion having a U-shaped channel disposed on one flange thereof, said channel being provided with outwardly extending flanges between which flanges and the flanges of the mullion-adjacent flanges or" window panes are disposed, of a U-shaped clamping member extending through enlarged registering apertures of the channel member and a.

flange of the mullion, the arms of said U- shapedclamping member terminating in curved flexible memb rs adapted to be forced into frictional engagement with the flanges vof the channel member.

In testimony whereof I aiiix my signature. I
